Preeclampsia and Intrauterine growth restriction (IUGR) remains as the important causes for the neonatal and maternal complications leading to even death in some cases. Uterine artery Doppler USG can be done transvaginally or trans abdominal and performed in the 1st or 2nd trimester of the pregnancy to detect these complications Doppler waveform suggested the high vascular resistance to blood flow. In our present study, we conclude uterine artery Doppler indices as prognostic procedure for the preeclampsia and intrauterine growth restriction. A cross-sectional survey design with convenient sampling technique was used. Mixture of standardized and self-modified structured questionnaire was undertaken to determine the indices of pre eclampsia and IUGR by uterine artery. The data was collected from Bahria International Hospital, Lahore during the period of 9 months. This study was included 162 pregnant females with identification of the main uterine artery on a longitudinal scan lateral to the uterus.  Initial diastolic notch of right and left side of the uterine artery waveforms was recorded. At every antenatal checkup, urine was tested for protein and blood pressure readings were taken to identify preeclampsia. Further analysis was done dividing patients as normotensive and those patients developing hypertension after 30 weeks of gestation. After delivery neonates observed for IUGR by head circumference and body weight. The study was concluded that from the total sample size of 162 pregnant females who undergoes uterine artery Doppler, 34% females shows diastolic notch and almost all of these later diagnosed with preeclampsia and 19.8% deliver babies with IUGR. So, based on the study, we have concluded that uterine artery Doppler is helpful to provide diagnosis of preeclampsia and IUGR in early pregnancy.

Background: Pregnancy induced hypertension (PIH) is associated with adverse perinatal outcome. Multi vessel colour Doppler studies are useful in these cases for timely intervention. The aim of present study was to know the significance of umbilical, middle cerebral and uterine artery Doppler in PIH and to analyse their role in predicting perinatal outcome.Methods: This is a study of 150 pregnant women with pregnancy induced hypertension (PIH). These patients were evaluated with colour Doppler and were followed subsequently for any adverse perinatal outcome.Results: Out of 150 cases 70% of cases were found in 20-30 years age group. 98 cases had abnormal uterine artery Doppler indices accounting for 65.3%, while 52 cases had a normal Doppler index accounting for 34.3%. Out of 150 cases, 94 (64.6%) cases had abnormal middle cerebral artery. In our study 53 cases had abnormal umbilical artery Doppler indices accounting for 35.4%, while 97 cases had a normal Doppler index accounting for 64.6%. Out of 150 cases in our study 27 cases had Reversal of a wave in ductus venosus waveform that is in 18%. In this study total 5 cases (35.7%) of perinatal mortality were seen.Conclusions: The knowledge of various doppler parameters may help to improve pregnancy outcome and identification of PIH at earliest gestation age as compared to other antepartum test modalities.

Background: Pre-eclampsia affects 2-5% of pregnancies and is a major cause of perinatal and maternal morbidity and mortality. Doppler is a non-invasive method for evaluation of feto-placental circulation without affecting pregnancy. A high resistance index in uterine artery Doppler waveform has been shown to be the best non-invasive screening test. Thus, we have conducted this study to find out the predictive value of transvaginal uterine artery doppler in early pregnancy for the prediction of pre-eclampsia. The aim of the study was early prediction of pre-eclampsia by trans-vaginal uterine artery Doppler study at 12-16 weeks.Methods: According to the study criteria 100 antenatal women between 12 to 16 weeks of singleton pregnancy attending out patient in the Department of OBG of S. D. M. Medical College Dharwad were included. After an informed consent, the women underwent ultrasound for dating and subsequently trans-vaginal ultrasound along with color doppler was performed to obtain uterine artery indices. These women were again rescanned at 24-26 weeks of gestation trans-abdominally and further followed up clinically for development of preeclampsia.Results: Out of 100 women, 22 patients developed preeclampsia. At 12-16 weeks 35% of women had bilateral uterine artery notching, mean RI was 0.57 and PI was 0.89. When uterine artery notch at 12-16 weeks alone was considered, 34.28% of women developed preeclampsia. Detection rate increased to 85.71% when RI>0.65 was also included along with notching. Uterine artery notching at 12-16 weeks gestation had 34.29% sensitivity, 84.62% specificity, 70.51% NPV. When notch and RI>0.65 considered together sensitivity and NPV increases to 85.71% to 98.25%.Conclusions: The uterine artery Doppler waveform indices at 12-16 weeks are the best non-invasive screening test available for early prediction of preeclampsia.
